MASS DEACIDIFICATION Meaning and
Definition
-
Mass deacidification refers to a process used to treat large quantities of acidic materials, particularly paper-based documents or books, with the aim of neutralizing their acidity and extending their lifespan. Acidic materials, such as those produced before the mid-20th century, tend to deteriorate over time due to the breakdown of cellulose fibers caused by acid hydrolysis. This degradation ultimately leads to the disintegration and loss of historical, cultural, or informational content contained within these materials.
To combat this issue, mass deacidification involves the application of an alkaline substance to neutralize the acid present in paper or books. This process usually takes place in specialized facilities or laboratories equipped with appropriate technology and personnel trained in preservation techniques. The documents are progressively deacidified by exposing them to an alkaline mist, vapor, or substance, which permeates through the acidic paper and adjusts its pH level. Often, deacidification is also accompanied by a complementary step of strengthening the document's physical integrity through other preservation methods, such as lamination or microfilming, to protect it from further damage.
Mass deacidification is considered a crucial element in the preservation and conservation of valuable documents and publications. By mitigating acid-induced degradation, it helps ensure the longevity and accessibility of historical records, literature, and other significant paper-based materials. This process plays a vital role in the preservation efforts of libraries, archives, museums, and other institutions that house and maintain vast collections containing invaluable information and cultural heritage.
Etymology of MASS DEACIDIFICATION
The term "mass deacidification" is derived from two main components: "mass" and "deacidification".
The word "mass" originates from the Latin word "masse", meaning 'a large quantity' or 'a heap.' It entered the English language via Old English and Middle English. In the context of "mass deacidification", the term implies treatment or process involving a large quantity or a significant number of items.
"Deacidification" is the process of reducing or neutralizing acidity. It comes from the Latin word "deacidificare", which comprises two components: "de", meaning 'to remove' or 'reverse,' and "acidus", meaning 'sour' or 'acid.
